Lol, I'm a Zerg user myself, and if you needed help on it I could teach you. I have a replay of destroying a Terran on fastest with superior micro, which is really great since anything owns Zerg on fastest maps... Unless your micro is yellow or xellos caliber and you can multitask like crazy, 5 pool is a stupid thing to do, because better people can beat that crap off with drones... Plus by the time the lings get to their base they will have at least 1 attacking unit, as well as the capacity to make more. 5 pool failure = automatic death unless the person you're playing does not know how to attack. When you're zerg you're supposed to bide your time until your base is built up... Before then, your unit production is basically twice as slow as the other races.

If you'd like to play tomorrow, I should be on at 5 EST or so. Look for me in the channel op Betrayed]; I'll be there unless I'm in a game.
